Title :

Observations on lek behaviour and the description of male scent disseminating structures of Callioratis abraxas Felder, 1874 (Lepidoptera: Geometridae)

Abstract :

Lek formation by males of Callioratis abraxas Felder (Lepidoptera: Geometridae) is reported.  The degree of sexual dimorphism in the species is described.  The scent dissemination structures in the males are reported and briefly described.  The possible functions of the above facilitating successful mating of the species is discussed and compared with similar lek forming by Ithomiine butterflies.  Questions regarding aposematic defences as a prerequisite for the successful forming of leks in Lepidoptera are raised.
